...Victor V. Lemeshko; Sergio Orduz Many electrical properties of insect larval guts have been studied, but their importance for toxicity of the Cry-type toxins has never been reported in the literature. In the present work, we observed potential-dependent permeabilization of plasma membrane...

...Carly Willenborg; Rytis Prekeris Segregation of the apical and basolateral plasma membrane domains is the key distinguishing feature of epithelial cells. A series of interrelated cues and processes follow this primary polarization event, resulting in the morphogenesis of the mammalian epithelium...

...Tytus Bernas; Jurek Dobrucki Redox activities associated with plasma membranes of nonphagocytic animal and plant cells have been reported by several authors. However, the natural substrates, structure and biological role of these putative enzyme systems are not known. Data indicating extracellular...

...Adilson Guilherme; Cledson Reis-Silva; Jorge H. Moraes-Albuquerque; Mecia M. Oliveira; Adalberto Vieyra The plasma membrane (Ca 2+ + Mg 2+ )ATPase is activated by acidic phospholipids in reconstituted systems. In this report it is shown that reversible phosphorylation of endogenous...

... rates. Here the influence of these solutes on sarcoplasmic reticulum and plasma membrane (Ca 2+ + Mg 2+ )ATPases is reviewed. The focus is on the changes induced by “perturbing” and “stabilizing” solutes at specific steps of the catalytic cycles of these enzymes, which can run forward (leading to ATP...

...Joseph H. Crabb; Paul A. Modern; Robert C. Jackson We have succeeded in reconstituting an exocytotically active egg cortex fraction by recombining purified cortical vesicles (CVs) with egg plasma membrane (PM). CVs were dislodged from a suspension of egg cortex by gentle homogenization...
